MARION O. YERKEY, OF WESTON, WEST VIRGINIA.

GUN-CLEANER.

Specification of Letters Yatent.

Patented May 31, 1910.

Application filed February 25, 1910. Serial No. 545,913.

To all whom it may concern:

Be it known that I, MARION O. YERKEY, a citizen of the United States, residing at Weston, in the county of Lewis and State of West Virginia, have invented a new and useful Gun-Cleaner, of which the following is a specification.

The objects of the invention are, generally, the provision in a merchantable form of a device of the class above specified which shall be inexpensive to manufacture, facile in operation and devoid of complicated parts; specifically, the provision of an oil cup adapted to be assembled with a cleaning rod for a gun, the said cup being arranged to engage the rifiing of a firearm, the movement of the cup in the rifiing producing a discharge of lubricant from the cup as it moves in the rifling; other and further objects being made manifest hereinafter as the description of the invention progresses.

The invention consists in the novel construction and arrangement of parts, hereinafter described, delineated in the accompanying drawings, and particularly pointed out in that portion of this instrument wherein patentable novelty is claimed for certain distinctive and peculiar features of the device, it being understood that within the scope of What hereinafter is thus claimed, divers changes in the form, proportions, size, and minor details of the structure may be made without departing from the spirit or sacrificing any of the advantages of the invention.

Similar numerals of reference are en1- ployed to denote corresponding parts throughout the several figures of the drawings.

is a detail perspective of the plug which is mounted in one end of the oil cup.

In carrying out my invention I provide, primarily, a plunger which, as shown in Fig. 1, comprises a section 1 which is assembled with the handle, and a section 2 which is assembled with the grease cup. Between the sections 1 and 2 may be introduced any number of intermediate sections 3, so that the plunger may be lengthened or shortened to conform to the length of the barrel of the arm. These sections 1, 2 and 3 are threaded to engage each other, as denoted by the numeral 11 in Fig. 2, further description of so common an expedient being considered unnecessary.

I further provide a handle 4 having in one of its terminals an axial bore in which is journaled for rotation one terminal of the section 1. Near to the end of the rod which is mounted in the handle 4, the said rod is diminished in diameter, as denoted by the numeral 5, and the handle 4: is provided with a radial channel 6 crossing the opening in the handle in which the section 1 is journaled for rotation. A pin 7 is introduced into the channel 6 and this pin, as clearly shown in Figs. 4.- and 5, is provided at its lower extremity with bifurcating arms which embrace the diminished portion 5 of the section 1, retaining the said section 1 against withdrawal from the handle 4, yet without interfering with its rotation in said handle.

I further provide a tube 8 which constitutes the grease cup of the device. This tube 8 is internally threaded from end to end, as denoted by the numeral 9. Rigidly assembled in any suitable manner with one end of the section 2 is a head 10 which is threaded to engage the threads 9 of the tube 8, the said head constituting a piston adapted to be advanced by rotation in the grease cup 8. The section 2 and the head 10 may be briefly denoted a supporting member for the grease cup 8. One end of the grease cup 8 carries a collar 12 which is threaded to engage the interior threads 9 of the grease cup. "This collar 12 has an axial bore 14 in which is slidably mounted the section 2, the said collar serving to maintain the alinement of the section 2 with respect to the grease cup 8 and to prevent undue strains upon the head 10 caused by the lateral movement of the section 2. The grease cup 8 adjacent the end remote from the collar 12 is provided with a plurality of ports 15 in its wall, the same being shown in Fig. 2 and with more particularity in Fig. 6. The end of the grease cup adjacent to ports 15 carries a plug 16 having a screw neck 18 which is threaded to engage the interior threads 9 of the grease cup, the screw 18 being of slightly less diameter than the body of" the: plug, sothat a shoulder is formed adapted to engage the end of the grease cup when the plug 1 6 is screwed home, as shown in Fig. 2. The exterior of the plug 16 carries a plurality" of ribs 17 which are adapted to register in the: rifiing of a firearm. It is to be understood that the; number and shape of these ribs 17 and their positions upon the exterior of the.

plug will be determined by the character of the rifl'ing ofthefirearmwith which the device is. to be used. This; plug 16 should be. fashioned from soft material so thati't. may travel the rifiing of'the arm without. injuring the same. The plug 16 is provided with an axial bore 19' which throughout a. portion of'its length isthreaded, as denoted by the numeral 20. In this axial bore 19 of the plug may be removably mounted any of the attrition elements which commonly form a part. of a gun cleaning outfit. shown most clearly in Fig. 3', may constitute one of these attrition elements. The rod 21 is provided with a threaded shank 23 adapted to engage upon rotation the threads 20 ofthe bore of'the plug, andthe said rod may be provided with a longitudinally disposed slot 22v through which may be passed a mg, the ends of'which may be permitted to ex.- tend rearward, covering the ribs 17 and the plug 16 and. extending beyond. the ports 15' in the grease cup. This application of a cleaning rag to a slotted. rod; is an expedient well known to: hunters and dealers in. firearms andit has not been considered necessary to show the rag applied to the device in the drawings.

Supposing the device to,- be assembled, as shown in. Figs. 1 and 2,.its operation is as follows: The spacebetween the piston IO'and the plug 16 isfillediwith any approved lubricant, preferably a somewhat heavy grease.

A cleaning rag is then inserted" through the 1 slot 22 in the member 1" and allowed to extend. rearward covering, ifdesired, the ribs 17 of'the plug and the.p.orts-,l5.inzthe grease I cup. The device-is then introduced into the bore of a rifle, the ribs 17 engaging the rifiing. By meansof the plunger comprising the sections 1, 2andr3. the oilcup may be forced to travel thebore of the arm, the ribs 17'folllowing'the rifiing and causing the oil cupto rotate in. the same manner as a projectile would rotate if following the rifiing, This rotation of" the grease cup causes the piston l0to advance, gradually forcingthe lubricant out of the ports 15 in the grease cup. It maybenoted that tl16 l12l11(ll6 4' is rotatably' mounted; upon. the plunger, the

function of this rotatable handle being explained' hereinafter.

When. the device. isused ashereinbefore. described the piston 10 should advance in.

A rod 21,

the grease cup 8 and in ordertha't the handle sections 1, 2 and 3 may not rotate in the handle thereby permitting the handle sections and the grease cup from rotating as an entity without advancing the piston, the fore finger may be extended beyond the handle 4 uporr the section 1 to preventthe rotation of the several handle; sections with the grease cup. should the friction between the piston 10 and the grease cup. 8,. be suflicient to overcome. the. friction between the handle et and the. sect-ion I.

The. foregoing is but one of the manyv applications to, which my invention maybe put- For, example, thepiston 10 may be. rotated into abutment with the. collar 12,.

binding the grease; cup. 8: against. independent-movement. In such case a. common. wire,

several handle secti'onsmay. be. grasped and the device. introduced into the rifiing of: a.

gun and reciprocated therein,.the' grease cup: being filled with a. lubricant. or not, as may be desired. Likewisetheipiston. 10 may be.

rotated into binding; relation with the collar 12,. so. that the. grease, cupmay. have no, independent movement, the device being, intro duced. HltO. the bore of. a gunv and reciproscated therein, the plvotal connection be tween. the handle section 1 and, the handle 4e permitting, theribs17 to traverse the rifling.

hen. assembled in this; manner it willbe seen that; the grease cup, whether provided. with the: attrition. member. or not, wi1l.tr.a-v.- ersev the rifiing, without discharging any. of.

the lubricant.

The device-may readily be separated. into its component parts and housed. in; small compass in the pocket of the operator.
